This work aims to analyze the process of Brazilian regionalization throughout the first half of the 20th century. For that, an analysis of the bases of construction of the regional planning and its relation with the organization of the beginning of Brazil-Republic, from the perspective of Historical Geography, is carried out. The operational procedure of the research was carried out in two moments: first a bibliographical search about concepts and themes was done, such as regionalization, natural region and regional planning. Secondly, documentary surveys were carried out on the regionalization plans developed in Brazil in the selected time frame, with an emphasis on the prospect of what would be consolidated as Brazilian regions. From this investigation, it is possible to observe the complexity in the regional adjustment arrangements of the State, as well as the role of regionalization in the search for the formation of the federative unit at the beginning of the last century.
